This video summarizes how to calculate probabilities when approaching pedigree and inheritance problems in Genetics.

thank you so much. i was very confused. Wish i had found this video before my first midterm

[masudanasir]

wow, this is actually the best video I watched about the pedigree calculating probabilities.

dr crowder is one of the best teachers I have ever had. so glad I took her for human heredity. really wish I could've had her for genetics.

Thank you so much for posting this video! I was so confused when it came to this topic and you cleared this subject up for me!

Why is it that this we didn't ignore the RR but added it to the probability making it 1/4 and rather not 1/3 for AA

[rahatamna]

Im confused, isnt the probability of the parents being carriers is 1/2?

[mariaorsic]

Fantastic! Do you private tutor? Be glad to do it on Skype or Zoom! I need help! Thanks!

Why A B are Rr heterozygous ? Why not RR and Rr

[hansanikularatne]

Could someone please answer this :
Why isn't the probability of being a carrier is 1/2 but 2/ 3?

1/ 4 = exhibits trait/ All
2/3 = carriers / the ones who do not exhibit trait.

Why is the denominator of second ratio shouldn't be 4? ( Which means out of all of them)

If impossibilities are removed when calculating the first ratio it would be 1/1 which is wrong. Why do u remove impossibilities only for the second ratio??

i dont understnad hwy we are just calculating probably that the parent is hetrogenous
